Summer is coming, and many of us will go to rest. Fans of diving and spearfishing, of course, will take this chance to do what they love, so we decided to devote this review to their favorite type of fishing. As you may have guessed, we will make an underwater gun.
Let's start with the author’s video
We will need:
- aluminum tube with a diameter of 10-15 mm;
- polypropylene tube of larger diameter than aluminum;
- old skewer;
- drill;
- a bolt;
- self-tapping screws;
- powerful rubber;
- epoxy resin;
The author of the idea preferred to make a collapsible hawka, consisting of two tubes 75 cm long.
The edge of the old skewer must be bent with the letter “G”. Also, approximately in the center, it is necessary to make a hole to get a workpiece, approximately as in the author.
Next, we make two holes for the bolt and hook on the polypropylene pipe.
We put a bolt in the hole made, making sure that the head of the bolt does not stick out.
Next, we strengthen with a piece of rubber and insert a metal billet, which was made from skewer.
We fix the workpiece with an elastic band.
When you click on the mechanism, the hook made at the end of the skewer comes out of the tube.
Now, approximately in the middle of the folded tubes, we make a small notch for the trigger.
The trigger mechanism of our speargun is extremely simple.
Next, we take powerful rubber and fix one end on the tube, and the other on the PVC tube.
Let's move on to making the harpoon. To do this, take a steel plate and weld on it three screws, as well as a bolt in the middle.
Now you need to connect the end with the tube. To do this, take a round piece of wood and glue the tip to it using epoxy.
Using the same epoxy, we connect the tip to the pipe.
If desired, paint the gun with spray paint.
After that, we have a full-fledged spear fishing gun.
